Stream overriding text properties set in RSD

I've gone through this forum and noticed that this is a common issue. However, I still couldn't figure out which part of the CSS overrides the properties. The specific webpage can be found at: http://www.asgmapping.com/news.html

The offending section is located in the bottom of the page. The paragraph font properties should be:
Font = Helvetica
Weight = Normal
Size = 14px
Line Height = 1.7

It doesn't seem to be the Stream since that's in Arial.
Have you tried changing the properties for this class in RSD:
<p class="paragraph">
...Or removing the "paragraph" and just using Helvetica for <p> in general?

The settings I set in RSD were the ones I listed (Font = Helvetica, Weight = Normal, Size = 14px, Line Height = 1.7). However, when the page is viewed in a browser the font properties that I set are not carried over. I assigned all paragraph elements into a class (paragraph-2). The ones in the other pages appear as expected. It is only in the page with the stream that it doesn't.

You might try simplifying your CSS. For example, set your p default, then add a more specific style as needed –
p.highlight, p.small, p.special-offer.... for example. Much easier to keep up with what CSS is being applied to what items.
Don't forget your <h> tags, you might want to use <h4> or <h5> to emphasize/separate a block of text.

Your suggestions gave me some insight on how the software works. I assumed that because Font was assigned to Helvetica (under Typography) that it will be automatically written to the CSS. However, looking at the Inspector showed that this is not the case. I assigned this paragraph it's specific Class, and then changed the Font to something else and the property was written to the CSS. I then switched it back to Helvetica in the Design tab so that Helvetica was written on the CSS.

I would have thought though that the default properties should be all written on the CSS already.
